HIGH SPEED STEELS

The group of high-speed steels includes all high-alloy tool steels that retain the necessary, high installed hardness of roughly 60 to 67 HRC at working temperatures of up to almost 600°C. Their service properties are partly attributable to the high carbide content, which results in very high wear resistance.

PROPERTIES & APPLICATION

• S 500/ AISI M42
Milling cutters, twist drills, tape, broaching tools, cold work tools.

Pressure casting moulds, cores, dies fornon ferrous products, tools for screws products, hot extrusion dies, lower dies, for valve cone products for pressing dies. Hot shear blades and trimmer dies for upsetting tools used in bolt, rivet nut and pin manufacturing, for heading punches, swaging dies.
It is suitable for oil and air hardening and it offers high hardness retention. It provides good resistance to hot wear and heat checking. Cold work tool steels are employed for the manufacture of tools for applications involving surface temperature of not more than 200°C.

Hot work toolsteel featuring excellent hot tensile properties, high hot wear resistance, adequate toughness and heat checking resistance; admits water cooling.

Heavy duty work tools and dies, mainly for light alloy processing: mandrels, dies, and containers for metal tube and rod extrusion equipment; tools and dies for the manufacture of hollow bodies, screws, rivets, nuts and bolts.
